Stargate Origins has revealed its cast, with Australian actress Ellie Gall joining the series while former Stargate Atlantis actor Connor Trinneer returning to the franchise.

Gall will play the younger version of Catherine Langford from Stargate (via TVLine), while Atlantis actor Connor Trinneer will play her father Paul Langford, after originally playing Michael Kenmore in Atlantis.

She later hired Daniel Jackson (played by James Spader in the 1994 film and Michael Shanks in the TV series) to discover the purpose of the mystical artefact.

The franchise had its origins as a 1994 movie, before being turned into a TV series with 1997's Stargate SG-1 and inspired two subsequent spin-offs, 2004's Atlantis and 2010's Universe, which had varying degrees of success.
